Expandable Tree Table

A data table for hierarchical records — folders, org charts, category trees — where any row can expand to reveal its children in place, indentation and a disclosure arrow showing depth without leaving the spreadsheet-like layout.

Files written

velocityx drops these into your project:

• components/velocity/standard-expandable-tree-table/ExpandableTreeTable.jsx

Peer dependencies

react — nothing else. Zero external dependencies is the point.

Theming

Colours come from the primary-* / accent-* Tailwind scales, so this drops into a project that is not Velocity without dragging our brand in. Install the contract once:

velocityx theme

Then set your whole brand in one place — raw RGB channels, not hex (a hex here silently breaks every opacity variant):

:root {
  --vx-brand: custom;
  --vx-primary-600: 220 38 38;
}

There is no component-level font-family anywhere in the library — your font cascade wins.

Licence

Commercial, for the duration of an active Velocity X subscription. The source is served by the licence-gated endpoint, never by the public CDN.
